FLOOR OB LIKE CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed July 15, 190-7. Serial No. 383,817.

To all wkomit may concern:

Be it known that I, HENRY NEILL WILSON, of Pitt'sfield, Massachusetts,have invented a new and useful Floor or Like Construction,-

which invention is fully set forth in the following specification.

This invention relates to improvements in the construction of floors,partitions, walls, doors, etc, and may be most readily explained andunderstood by reference to the accompanying drawings, illustrating whatis now believed to be the preferred embodiment thereof as applied, forexample, to a floor of a fireproof building.

Fi ure 1 is a perspective view of part of the meta lic portion of thefloor, one of the supporting girders or beams being also shown;

ig. 2 is a transverse section through a portion of the finished floor;and Fig. 3 is a perspective view of a connection-device.

The floor illustrated in the drawing comprises metallic sections, eachcomposed of a single sheet of metal, preferably galvanized sheet steel,bent to form a succession of preferably triangular cells such as 4, 5, 6and 7, for example, the upper and lower faces of the cells presentingapproximately parallel surfaces to which plaster, concrete -or the likemay be applied as hereafter explained.

us, in Fig. 2, for example, the lower faces of alternate cells 5 and 7present a surface approximately parallel to the surface presented by theupper faces of alternate cells 4 and 6; italso follows, as clearlyshown, that the positions of succeeding cells are reversed, one cell,such as 4, pointing toward one surface the next cell toward the othersurface,

and so on. In assembling a number of such sheet metal cellular sectionsside by side, the side cells are preferably interlocked by engaging theedge 8 of one section within the edge 9 of the adjacent section, asshown for example in Figs. 1 and 2. In order to provide suitable gripfor the plaster, cement or the like, each cell is provided at itssurface with a dove-tailed groove 10, which forms a key for the coveringof plaster, cement or the like.- As shown in Fig. 2, alternate cells 5and 7 are left open along their upper or narrow edges for the receptionof a filling of cement, mortar, concrete or analogous material (forconvenience, hereafter designated stone-like material) capable ofsetting to form within said cells stone-like connecting bars 15 betweenthe floor above and the ceiling below, said stone-like bars preferablyalternating with hollow air-filled cells, such as 4 and 6, for example.These air-filled or dead-air cells, instead of being left open for thereception of a filling of cement, mortar or analogous material, as inthe case of cells 5 and 7, are closed, the bonds or angles 30 and 31 inthe sheet metal being in contact. Concrete, mortar, or analogousmaterial, applied to the lower surface of the metal in Fig. 2, forexample, is thus excluded from the cells 4 and 6, which are intended toremain hollow and constitute dead-air cells. Furthermore, the closing ofintermediate cells by contact of angles 30 and 31 with each other, addsstrength and rigidity to the structure.

When the construction is used for the floor of a building, asillustrated in the drawing,

plaster 11 formin the ceiling may be ap lied to the under su ace of themetallic cel ular sections, being held securely in place by engaging thekey-grooves 10. T e fioor surface may be composed of a covering ofconcrete or other stone-like material 20, preferably the same as used toform the filling for the cells 5, 7, etc, applied to the u per surfaceof the metallic sections and ing into the key-grooves 10 of saidsurface. floor-covering, wood, tile, or the like, may be superimposed onthe stone-like base. In filling the cells 5, 7, etc., I may, if desired,introduce tubes or pipes 12, to be used as conduits for electric wires,or for any other purpose which the convenience or character of thebuilding may suggest. These pipes are preferably of such size as to passinto the cells through the openings along the upper edges thereofthrough which the stone-like filling is introduced.

In a floor, partition or the like, constructed as above described, thestone-like bars 15 constitute rigid, strong and durable connecting andsu porting ribs between the op osite surfaces 0 the artition, or floor,rei orced on either side y the metallic Walls of the cells. Some of thecells bein hollow, spaces are thus afforded to permit a l necessaryexpansion and contraction without injur to the construction, while thepresence 0 the stone-like bars at the same time prevents collapse,buckling or the like of the cellular meta lic part of the structure,particularly under severe strains, variations in temperature, etc.

In Fig. 2 I have illustrated a number of sections abutting end to end uon a supporting beam or girder 13, and old in proper re ative positionby connection devices 16,

The final which forms a part of my present invention. Theconnection-device 16, see Fig. 3, consists of a piece of sheet-metal,preferabl galvanized steel, bent to form wings or anges 17 and 18 searated by an interposed dove-tail rib 19. his rib is of such exteriordimensions as to slide,into the ends of the under cut key-grooves 10,permitting the connection-devices to be brought to the positions shownin Fig. 2, the wings or flanges 17 and 18 of adjacent devices closely aproaching each other to hold the cells of t e metallic sections inproper relative upright positions until the intermediate open sidedcells are filled with the stone-like material which sets to form thebars 15 What I claim is:

1. A floor, partition or the like, having sheet-metal bent to form asuccession of side- .by-side approximately triangular cells presentingopposite floor, wall or like surfaces,

' the position of succeeding cells bein reversed and some of the cellsbeing close and hollow and other cells being open and filled with astone-like material forming between said op osite surfaces connectin andsustaiping are separated by the ho ow closed cel s.

2. A floor, partition or the like, having sheet-metal bent to form asuccession of sideby-side approximately triangular cells presentingopposite fioor, wall or like surfaces, the position of succeeding cellsbeing reversed and some of the cells being closed and hollow and othercells being open and filled with a stone-like material forming betweensaid opposite surfaces connecting and sustaining bars separated by thehollow closed cells, and a covering of plaster, cement or the likeapplied to one or both of said surfaces.

3. A floor, partition or the like, having sheet-metal bent to form asucdession of sideby-side approximately triangular cells presentingopposite floor, wall or like surfaces, the positlon of succeeding cells1 being reversed and all of the cells being closed at one of saidsurfaces but intermediate cells being open at the other surface, saidintermediate cells being filled with a stone-like material formingbetween said opposite faces connect ing and sustaining bars separated byhollow closed cells.

5. The combination with opposing ends of two cellular sections, eachsection formed of sheet-metal bent to form a succession of hollow cellsresenting op osite floor or wall surfaces, sai sections eac having atone of said surfaces one or more keygrooves adapted -to be brou ht intoalinement, of a connectiondevice avin thereon a rib adapted to fit intothe ad acent ends of two alined rooves of the two sections.

6. T e combination with opposing ends of two cellular sections eachsection formed of sheet-metal bent to form a succession of hollow cellspresenting opposite floor or wall surfaces, said sections each having atone of said surfaces one or more key-grooves adapted to be brought intoalinement, of a connection device havin a rib adapted to fit into theadjacent endso two alined grooves of the two sections and one or morewings each adapted to approximate contact with a HENRY NEILL WILSON.
